But they're everywhere. If you are tanning at noon, 65 billion neutrinos from the sun will pass through every square centimeter of you each second without any measurable interactions with the molecules of your body.

An artist's conception, based on a real image of the IceCube Lab at the South Pole, a distant source emits neutrinos that are detected below the ice by IceCube sensors.

Backtracking the path through IceCube indicated where in the sky the neutrino came from, and automated alerts notified astronomers around the globe to search this region for flares or outbursts that could be associated with the event. Using a vast array of telescopes in space and on Earth, they have identified a source of cosmic rays-highly energetic particles that continuously rain down on Earth from space. According to the previous data records a highly energetic neutrino collided one of the nuclei which were of those frozen water atoms in September 2017, which resulted in the creation of a particle which is specifically called a muon and it was then passed through the chilled detector, which allowed scientists to find the real trajectory from where the neutrino had arrived to the South Pole.

According to the experts, this recently found alien neutrino has come from a supermassive black hole, located near about 3.7 billion light-years away.

Neutrinos, always accompanied by the photons, possess no charge, so unlike the electrically charged particles of cosmic rays that can be deflected by cosmic magnetic fields, they can travel through the universe without detours. Because they rarely interact with matter and have almost no mass - they are sometimes called "ghost particles" - neutrinos travel nearly undisturbed from their accelerators, giving scientists an almost direct location of their source. This eruption of the blazar could also be detected with other observations - from radio radiation to gamma radiation. Therefore, one of its main components is a cubic kilometer of this ice, under the continent's surface, near the NSF South Pole research station.

This high energy strongly suggested that the neutrino had to be from beyond our solar system. Neutrinos interact very weakly with other matters. A specific feature of blazars is that one of these jets happens to point towards Earth, making its emission appear exceptionally bright. The neutrino we're talking about had an energy of about 300 teraelconds - more than 40 times what the protons in the largest particle accelerator in the world have reached. This particular blazar, known as TXS 0506, was at a long-term peak of activity at that time.

Not only that, but as neutrinos travel practically unhindered through the vastness of space (unlike other particles, neutrinos only interact via the weak nuclear force) they have the potential to map the sky like astronomers now do with light at differing wavelengths, but at higher energies.

Blazars are thought to generate neutrinos and gamma rays, possibly explaining at least one source of cosmic rays. NASA's Fermi Gamma-ray Space Telescope and the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) Telescope in the Canary Islands. Scientists need to studymore such neutrino events and link them with other sources to really understand how the process works. Scientists claim that it is better still than X-ray vision (had by astronomers for decades) and the neutrino also gives the key to unlock the door that opens the ghostly side of astrophysics. "It is accurate to say that we are all swimming in neutrinos".
